KEP instructions call for a fabricated muffler mount that attaches to the right hand head of the Subaru EJ22 engine. Not many people have access to welders and fabrication facilities, but we do.
These mounts are not rocket science but a real pain in the
backside to manufacture in small quantities. The assembly has
to be be quite accurate so they fit tight.
The muffler mount attaches to the right head and to the exhaust manifold studs at the bottom.
The majority of the vertical load is taken on the top of the
head - using the spare mounting hole on top. The exhaust
manifold studs provide the lateral support and really do not
see much vertical load..
